The scsi interface metc vs squirrel scsi conflict

[rampartsagain]

Hi dear friends,guru´s and retro maniacs

the question is how do i disable accelerator card mtec internal scsi and let squirell scsi active ,since with my mtec rtc card it disables the squirrel interface and don´t detect cd rom ,also i am geting not enough memory when try to use os 3.5 install cd ,in my os 3.5 pre installed cf card says not enough memory to run istaller and some odd errors,plus the cd player of squirell the interplay don´t let read audio cd says can´t detect cd.interface i think?

[roy bates]

hmm.why would you want to use the squirrel over the scsi on the mtec anyway?

[rampartsagain]

hi roy because my mtec doesn´t have the scsi adapter

[roy bates]

thats strange the scsi was on a seperate card wasent it? on the mtec was it also called the viper 1230/28 rtc or something like that.

so you should be able to use the squirrrel anyway i would imagine.

have you tried using the software thats with idefix97 just to see if one or both show in the system?



is there any chance of a couple of pictures to verify the card?

according to amiga resource http://amiga.resource.cx/exp/t1230

the mtecscsi.device is the scsidevice for the accel card and think
and squirrelscsi.device be the device to use for the squirrel at a guess

yes but surely the one cant conflict with the other if ones not there?
unles its in the bootrom of the card maybe.

[rampartsagain]

i don´t use idefix as it is not a 4 buffered way ide device, in sys info mtec appears as zorro 2 ,therefor i assume it was installed by the istallation floppy ,i just want to know if in case any drawer that has the scsi devices has the 2 ones installed.

the card is this :

hope this helps

i sory the links but it is giving me monster images since i didn´t do resize

i think is an instalation of scsi conflict because if i take the card out detects the cd rom with it in ,disables me scsi detection of the squirrel cdrom ,also the audio interplay music player don´t work with the squirrel software with the accelerator unpluged

[roy bates]

ok.

i suggested using the idefix programme to see if the scsi from the card shows in the system i dident mean for you to use it with scsi in anyway if you see what i mean as some accelorators dont need the scsi to be there in hardware for it to show in the system.



if i could ask a couple of questions.as i dont have one of these.


did the accelerator come with an install disk?to install software to harddisk for the card.i cant see this being the problem but you never know.bearing in mind the scsi part of the card isent actually there.(the adaptor is the scsi)
if you have used the scsi install disk uninstall it,and try again.


have you tried to get a hold of a later version of the squirrel drivers,again i dont think this is the problem unless the mtec interferes with the pcmcia port in some way.


i beleive that the scsi of the mtec is in firmware on the card a bit like the apollos even if its not there in hardware,if this is the case i dont think you will be able to resolve this.


thats why im asking if the scsi for the card is showing in the system in the os.even if its not there the two devises would have two different names in the os wouldent they?



lol.......yes the original pics where a bit big to look at, they where hhhuuuggeee.

[cosmicfrog]

a few things to try see what devices are there
run HDToolBox and see if both scsi devices are listed
run sysinfo - click on devices
run scout - click on devices

good idea mate

[rampartsagain]

i will try when i woke up come from work now has been a busy work night i will reply when i get out of my coffin

[sneeker]

I see the problem here as the mtec is a rebadged viper
Has the cards firmware been upgraded at all?

Viper's arent pcmcia friendly if Kickstart 3.1 (Or workbench 3.1 on 3.0 roms) is being used, theres a firmware update for them that supposedley fixes the issue. But Im sure Ive read theres problems with ram with them after being upgraded.

yeah i read something about 128mbs simms or some other thing and pcmcia but cant remember where it was

[rampartsagain]

well friends the i haven´t been able to try since i am with a pera putnick project in hands ,mtec is a german made accel model the good thing is that i can trust my volkswagen not so sure about the card is a pitty to put a 130 euros card stopped because of the scsi adapter not beeing used,i tryed to buy on ebay the only one i found but the lady was selling his housband hardware and was not using paypal through ebay i was not beeing protected by costumer serviçe she sayed that i make many questions on not using paypal through ebay,if i was next to her i will take the crap out of her ,i was beeing fooled and i was the one making questions.

[rampartsagain]

well like joker said on batman one "honey you will never believe what happened to me today "

guess what with my mtec card out adf transfer kit detects cf cards with mtec on card not detected maybe dosdrawer cf0 defs ????

[roy bates]

yep sounds like a firmware issue,just as sneeker said.


where would you get a firmware update for one of these?

[rampartsagain]

that is the problem roy i am thinking of doing a revision on the startup sequence,trying to disable the responable for that issue.
those boards where full of bugs damn!

@rampartsagain

It looks to me as though you are missing the SCSI component for the accelerator card

depending on you version you either need

Version 1

(stock photo: amiga.resrouce.net)

Version 2

(stock photo: amiga.resrouce.net)

Without the SCSI daughter card, there simply wont be any SCSI.

These Adapters dont use DMA transfers so while they will be quicker than the Native IDE, it wont be by much... I suspect 2.5 - 3MB will be the maximum that can be pulled.

You can have multiple SCSI hosts in your system, "mtecscsi.device" and "squirrelscsi.device" the software to consult these devices is the scsi.device which needs to be updated (to the one that comes with IDE Fix) or patched, like the one in Classic Workbench

[rampartsagain]

zetro thanks that is not the point the point is the pcmcia neither work with the cf adapter that is strange since is not just the scsi devices

but thanks for your help plus i have idefix disk but why it disabeled pcmcia???

[roy bates]

can you try something?


boot up workbench and "leave out" the CF0 dosdriver from devs,then reboot.

when it has booted click on the CF0 icon(while the cf card is plugged in) to mount it,just to see if the card shows in the system.

[rampartsagain]

i think i already tryed that out it says mounted but i will try again

[Zetr0]

@rampartsagain

Sorry, I must of missed the question..

Anyway, its quite likely you need CC Rest fix installed - alternatively amgiakit offer a PCMCIA fix

[rampartsagain]

nothing to appologise my friend i think we are digging here some questions that must have been fixed some 10 years ago ,i think also should be created some data bank were we could check with time this issues anyway today have no time to check keep in touch
best wishes for all

[sneeker]

Pcmcia is disabled by workbench or kickstart 3.1 and above if there is memory at a certain address (Somewhere around 8mb iirc) this address is used by the pcmcia port, but some expansion cards also use it, so if theres memory allocated at the same address as the pcmcia port it disables the pcmcia port.
Cards like the blizzard and other pcmcia friendly cards iirc dont map memory to the pcmcia address and therefore it still works.

Updating the firmware should be a fix to stop using the same address as the pcmia port, but as I said earlier, from what Ive read elseware it basically disables the memory on the card. Which makes it pointles even having the card in.

Hope that makes a bit more sense.

[roy bates]

yes,but where to get these firmware updates.

does anyone have a link?

[rkauer]

The problem is the Mtec memory will clash with the Amiga PCMCIA (cardresource.device, which is inside the kickstart ROM), so a Zorro2-only card (as the Mtec is) will make the PCMCIA port unusable when more than 4Mb of RAM is installed.

There is no firmware upgrade for this accelerator, but there is a new PCMCIA "driver" (cardresource.device) that can be installed as a software module that maps the PCMCIA outside the Zorro2 address.

This will be transparent to any PCMCIA card hooked to the A600/1200.

I think Marios (mfilos in this very forum) have the archive and instructions on how to install it.

[rampartsagain]

well i think mfilos made it i know custom kickstart is agains eab policy but in this case is needed i have original kick 3.1 on my amiga 1200 with os 3.5

read this:

http://www.amiga.org/forums/archive/...p/t-60108.html

if mfilos can´help i would like to pm me for custom 3.1 kick as my mtec is blocking the pcmcia

[sneeker]

http://amiga.resource.cx/exp/cobra

I believe theres a firmware update in one of the files (dkb.ferret.dms) Going to have a look later..

In the READ.ME File, it says, updated code to correct for a problem with 3.1 and memory on the accelerator card,. Also added and updated version of ReMapKS that works with the new code.

But it doesnt tell you how to update lol.

In C theres a file called flash that has to run from the cli, the FlashCode drawer has the update....

Im not brave enought to do it though yet.

[rampartsagain]

sneeker but that says cobra accelerator and we are talking about mtec is it the same hardware compatible ????

this is true i changed the edo by a 4mb sim edo i had from old computers and detected the pcmcia card ,do anyone have a custom 3.1 without this issue?????????

any help i am ready to burn the 2 kickstart chips .....
